✔ 最佳答案
簡答: 鰓.
長一點答: 佢有兩個心臟將血泵到兩個鰓, 收集離開鰓既血管再有一個心臟將血泵全身. 所以, 八爪魚有兩個鰓三個心臟.
再詳細d: http://en.wikipedia.org/wiki/Cephalopod 自己睇下啦.

章魚,又稱石居,八爪魚,是軟體動物門頭足綱章魚目動物的總稱。 章魚有八個頭足,頭足上有許多吸盤;有時會噴出黑色的墨汁,幫助逃跑。

章魚有相當發達的大腦,章魚可以分辨鏡中的自己,也可以走出科學家設計的迷宮,並且吃到其中的螃蟹。

係用鰓的~

--> Octopuses have three hearts. Two pump blood through each of the two gills, while the third pumps blood through the body.

--> Octopuses draw water into their mantle cavity where it passes through its gills.

--> As mollusks, octopuses have gills that are finely divided and vascularized outgrowths of either the outer or the inner body surface.
